Last year the Office of National Statistics produced a separate 'top 100' for England, one for Wales and combined England & Wales one, this was the first time they'd done this (usually they only produced the combined one).
If you go
http://tinyurl.com/34q4yqu and click to open the files '2008 Boys'/Girls' Baby Names by country, region and month', the third sheet in each file is a Top 100 for Wales for 2008. The 2009 data isn't out yet.
